HI, i'm kinda new to doom modding and while i'm getting the hang of coding i can't for the life of me do anything art related

i really have no idea where to start, like is there a commission process or something(i'm mostly joking, but damn would it make this easier and faster)

I'm making a mod where you play as a little girl trapped in hell and while i have all but three weapons planned i'll just post what i currently needsorry if i'm asking for too much or if i'm asking wrong

Spoiler:

Yo-Yo - melee weapon that replaces fistSprites Needed-Yoyo in hand-yoyo being fired - i feel it would work better as a projectile, but i'm still a noob

Bubble Gun - fires a stream of bubbles - hold for large bubbleSprites needed based on this toy-the gun being held by a little girls hand-the end of the gun turning-the bottle for ammo

Crayon Cannon - fires crayons like the chaingunSprites i need-a chaingun like weapon where the different barrels are based of the 6 main colors in order Red, Orange, Yellow, Green, Blue, Purple-a Crayon Projectile for each color

Pet Collar - Summons a friendly allySprite i need-Simple red pet collar in her hand with the golden tag near her thumb-her using her thumb to flick the collar to switch the summon-different tags with a dog symbol, cat symbol, bunny symbol, and cacodemon symbol
